Frac job reports can look mysterious, but you can learn to understand them.

Slides excerpted from my upcoming class in Colombus, Ohio on Fracturing.
(There are some slides left out, so the slides may not "flow" from one to the
next).
The word “stage” is used to mean two different things. This
confuses everybody, and it has been this way for at least a
quarter-century.
FRAC REPORTS
• If you work for
an oil company,
you may deal
with frac reports.
• These
documents may
look
complicated, but
don’t despair!
I’ll use “fluid stage” and “perf zone stage.” There is no
standard terminology.

FRAC REPORT
• Pump schedule is one of the most basic pieces of data
• Stages here are the small “fluid” stages within a larger
“perf zone” stage

VOLUMES SUMMARY (for all perf zone stages in a
particular well)
FRAC REPORT
Slickwater: water with a little polymer added, but the polymer is not cross-linked to
viscosify it. The main frac fluid in this case. Creates the fracture and carries the sand in.
HCl: Hydrochloric acid. Pumped before pumping the slickwater. Removes debris
from perforation tunnels to improve connection to reservoir.
